Separate Shell Session

Some features allowed with SCP protocol are not supported by
SFTP protocol. This includes execution of
remote command and
direct duplication of remote file. To support
these features with SFTP protocol,
WinSCP can open a separate shell session, to perform the commands on. The shell session is
opened automatically (with suppressible confirmation)
when you attempt to use any of the mentioned features. After the command is executed,
the shell session will be kept in background for future use.

For the feature to work, WinSCP must be able to open a shell session similar to one used by
SCP sessions. So while you are using
SFTP protocol, you may still need to
alter options on the SCP/Shell tab of the Login dialog
if the defaults do not work. Also, for the feature to work, the shell must use the same path syntax
as the SFTP server.
